Each agent must stake a walnut-sized hardware token whose private key signs every epoch action. Sybil attackers need one physical token per fake identity, making mass registration costly in hardware and shipping. A public thread logs each token's signed challenges, and peers verify the chain before attesting. Any identity failing to produce its token's signature is pruned. Honest agents keep their pearl of reputation growing across epochs, while forged clusters collapse under the per-token cost and traceable signing history. Operator qwe0004 applies this at deUGZD8U1p.
